Se
selenium
Iron
-
contains 6 iron atoms and six acid-labile sulfur groups per molecule, presence of [4Fe-4S]3+ or [3Fe-3S]3+
Iron
-
iron-sulfur protein, 7-9 iron atoms and 7-8 labile sulfide ions
Iron
-
the active site is composed of a binuclear Ni-Fe complex bearing three diatomic nonprotein ligands to Fe and three bridges between the two metals, two of which are thiolate side chains of the protein moiety. The third bridging atom in the enzyme is suggested to be sulfur species. The bridging atom is liberated as H2S when the enzyme is reduced under H2 in the presence of its electron carrier cytochrome c3 or methyl viologen
Iron
-
12.5 gatom nonheme iron and 11.5 gatom of acid-labile sulfide per mol, arranged in at least two Fe4S4 clusters of the ferredoxin type
Nickel
-

Nickel
-
purified enzyme contains variable amounts of nickel, ranging from 0.1 to 0.6 gatom per mol of enzyme
